减速机一般用于低转速大扭矩的传动设备，把电动机、内燃机或其它高速运转的动力通过减速机的输入轴上的齿数少的齿轮啮合输出轴上的大齿轮来达到减速的目的，普通的减速机也会有几对相同原理齿轮达到理想的减速，大小齿轮的齿数之比，就是传动比。Reducerisgenerallyusedindrivingequipmentoflowspeedhightorque,largegeargearoutputshaftpowermotor,internalcombustionengineorotherhighspeedrunningthroughthereducerinputshaftlessnumberofteethonthereducertoachievethepureofgeneralreducerwillh***eseveralpairsofthesameprincipletoachievetheidealeffectofgearreducer.Thesizeofthenumberofteethofthegearratio,thetran***issionratiois.减速机的作用1)降速同时提高输出扭矩，扭矩输出比例按步进电机输出乘减速比，但要注意不能超出减速机额定扭矩。2)速同时降低了负载的惯量，惯量的减少为减速比的平方。大家可以看一下一般电机都有一个惯量数值。Thefunctionofthereducer1)reducethespeedandincreasetheoutputtorqueatthesametime.Theratioofthetorqueoutputtothemultiplyinganddeceleratingratioofthesteppermotoroutput,butwemustbecarefulnottoexceedtheratedtorqueofthereducer.2)speedreducesinertiaofloadatthesametime,andinertiareducestothesquareofdecelerationratio.Asyoucansee,generalmotorsh***eaninertiavalue.减速机动力源运转速度根据在不同转速条件下对减速机的试验表明，随着减速机输入转速的增加，噪声也将增大。Theexperimentalstudyonthestructuralformofthereducerboxshowsthatthecylindricalboxisadvantageoustovibrationreduction.Underthesameotherconditi,thenoiselevelofthecylindricalboxis5dBlowerthanthatofothertypesofboxon***erage.)
